The site is one of the few areas of unimproved marshy grassland in east Hertfordshire. It is crossed by a stream and has a rich diversity of vegetation, including a variety of orchids.[1] Kestrels often hunt mice and voles, which are common on the site.[3]
There is access from Beckfield Lane next to the house called Blagrove. In some areas there is treacherous deep mud.
